 * \brief Mram2 Click example
 * 
 * # Description
 * This example demonstrates the use of MRAM 2 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver, sets the write protect and disables the hold signal.
 * 
 * ## Application Task  
 * Writes "MikroE" into the first 6 memory locations, and then reads it back 
 * and displays it to the USB UART approximately every 5 seconds.
